The invention relates to improvements in hoisting slings especiallyadapted and arranged for use in conjunction with hoisting apparatus, theprimary object of the invention being to provide a simple and efiicientdevice of this character, capable of economical construction and highlyetlicient in use.

Another object of the invention is the provision of a hoisting sling ofthe character indicated, so constructed and arranged-as to preventinjury or damage to the. packages hoisted.

Another object of the invention is the provision of a hoisting sling ofthe character indicated, having improved means of attachment orconnection with a hoisting element.

Other objects will appear hereinafter.

The invention consists of the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings forming a part of this specification, and in -which V Fig. 1 isa perspective view of a hoisting sling embodying the invention, andshown in position of use, and r Fig. 2, a similar View of a modifiedform of construction.

The form of construction illustrated in Fig. 1 of the drawings comprisesa relatively wide flexible belt 3, preferably of cotton, leather, or thelike, and adapted and arranged to embrace or encircle the objects orarticles to be hoisted. The belt 3 is provided at one end with aback-turned loop, or flap, 1, se-

cured thereto as indicated by suitable rivets, and forming a securingloop 5. A transverse rod is mounted as shown in the loop 5, said rodbeing provided at opposite ends with eyes 6, swiveled to the ends 7 ofthe flexible loop 7 preferably in the form of a wire rope,

or cable, has its ends securedto the eyes 6,

and is adapted and arranged to detachably engage the hook at the end ofa hoisting cable 9 or the like.

The strap 3 is provided at its other end also with a back-turned flap10, forming a securing loop 11, in which is mounted the transverse rod12' having protruding ends bent'to or objects, such as'sacks of sugar,grain, and u p the like, ior hoist ng purposes, and which .jVlll nottear or Cllll Sitld SaCliS, or other objects 192.0. Serial No. 472,304.

,form hooks 13, adapted and arranged to slidably engage the sides 01':the loop 7 as shown. by this arrangement, aslip-noose is formed whichmay be readilypl'a-ce'd around articles engaged. The sling disclosedwill be found to be especially adapted for use in loading and unloadingships; is of great strength; is waterproofjand',nonkinkable; and may bereadily applied to or reniovedfrom the object hoisted. Thewire, cables,or ropes, in

the sling,n iay be readily replaced when necessary, and the slingwlllthus last a long time.

7 1 second flexible loop 1 1, preferably of rope, is also passed throughthe securing loop ll,and twisted togetherat15 and forming an eye 16.Another loop 17 also preferably of rope, is passed through the securingloop 5, as

shown. MAS the sling is emptied, the loop 1 1- 16 is looped through theloop 17, and the sling is 'returned to loading position by engaging theloop 17 with the hook 8. The loops 1l-16 and 17 may also be employed toadvanage in manipulating the sling when placing it around or removing itfrom the object' to be hoisted. This form of the device is especiallyadapted for use in loading into railroad cars or narrow quarters Wherethe belt is liable to be rubbing against doors, and the like, and thuswearing out.

In the form'of construction illustrated in Fig. 2, the'belt 3 isprovided at each end with triangular metal loops 18 and 19 secured tosecuring loops 11' and 5, as indicated. The loop 18 passes through atubeorpipe 18 which prevents rubbing against loop 11 and furnishesadditional reinforcement. The loop 19 is adapted and arranged to engagea double hock 2O loosely pivoted at the apex of the tringular metallicloop 21, adapted and arranged to slide upon the body of the belt 30, asshown, the base .of the loop 21 being provided wih a roller 22 tofacilitate such slidingj This arrangement forms a simple and efilcientslip-noose construction which may be readily applied to or removed fromthe objects to be hoisted. This form of'con-- 100 struction isespecially adapted for use in situations Where there is no especialdanger of rubbing, and is especially adapted for use in loading suchthings as lumber, paper, etc., Where there is little or no. swaying orswinging against sides of the hatchways of the ship, or the like. Theloose hook 20 Will not tear or mar the enclosed objects or other partsof thesling. f

While I have illustrated and described the preferred forms ofconstruction for carrying my invention into effect, these are capable ofvariation and modification Without departing from the spirit of theinvention. I therefore do not Wish to be limited to the precise detailsdisclosed, but desire to avail myself of such variations andmodifications as fall Within the scope of the appended claims.

' Having thus fully described my invention, What I claim as new anddesire to secure by Letters Patent is:

1, A hoisting sling comprising a flexible I belt; metal loops securedto'the ends of saidbelt; and a loop slidable on the body of said belt,and having a hook detachably engaging the loop on one end of said belt.

.2. A hoisting'sling comprising a flexible belt having its ends turnedbackwardly upon itself to form securing loops; triangular metal loopssecured in said securing loops a triangular metal loop slidable on saidbelt, a hook being formed at the apex thereof'to detachably engage oneof the loops on an end of said belt; and a roller mounted on the base ofsaid slidable triangular loop, said roller slidin against said belt. 7

n Witness whereof, I have hereunto set my hand this 21st day of July,1930.
